android中的流媒体问题

这个方法在我的应用程序中有效,非常简单。在你的 onCreate()

          TelephonyManager telephonyManager;
        PhoneStateListener ringListener;

        // Get the telephony manager
        telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

        // Create a new PhoneStateListener
        ringListener = new PhoneStateListener() {

          @Override
          public void onCallStateChanged(int state, String incomingNumber) {

            String stateString = "none";
            switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:
              stateString = "Idle";
              break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
              stateString = "Off Hook";
              break;
            case TelephonyManager.CALL_STATE_RINGING:
              stateString = "Ringing";

            Log.i(TAG, "TELEPHONE RINGING!!");                          

              //Do stuff here when phone ringing detected


            break;
            }
           }
        };

        // Register the listener with the telephony manager
        telephonyManager.listen(ringListener, PhoneStateListener.LISTEN_CALL_STATE);


        //End create a new PhoneStateListener
